LockChime.wav plays on lock, not unlock
Tesla plays your custom LockChime.wav when you lock the car. There is no separate UnlockChime.wav — the factory confirmation tone still handles the unlock event.

How it works
How the Tesla unlock chime works
Four things to know before you install — so you get sound on the first try.
One file, one trigger
The feature is called 'Lock Sound' in Toybox. It fires on the lock event only. If you want something to play when you approach the car, the factory unlock tone is what you hear.
Boombox must be set to USB
Your custom file only plays when Toybox → Boombox → Lock Sound is set to USB. Leaving it on Default plays Tesla's built-in preset instead.
Volume is independent from media
Adjust the lock-chime volume in Toybox using the Boombox slider. It is completely separate from your media volume — set it once and it sticks.
Compatibility
Which Tesla models support a custom lock sound
Custom lock chimes work via Tesla's Boombox feature. The requirement is an external pedestrian-warning speaker, which shipped on these models.

How to set a custom Tesla lock sound
Step 1
Download your lock sound
Pick any sound below — every download arrives as LockChime.wav at 44.1kHz 16-bit PCM WAV. WAV is the required format; the 44.1kHz/16-bit spec is recommended for clean playback.
Step 2
Create a Boombox folder on USB
Format a USB drive as FAT32 or exFAT. Create a folder named Boombox and place LockChime.wav inside it. Full path: Boombox/LockChime.wav.
Step 3
Plug into the front USB-C port
Insert the drive into your Tesla's front USB-C port. Wait two to three seconds so the car indexes the drive before opening Toybox.
Step 4
Switch to USB in Boombox settings
Open Toybox → Boombox → Lock Sound and change the source from Default to USB. Lock the car to hear your new custom chime.

FAQ
Tesla unlock sound — common questions
Is there a separate Tesla unlock sound file?
No. There is no UnlockChime.wav feature in Tesla firmware. The official 2026.8 and 2026.14 release notes do not list separate unlock sounds. Your custom LockChime.wav plays when you lock the car; the factory tone handles unlock.
Why isn't my Tesla playing the custom lock sound?
Two things to check: (1) Boombox source must be set to USB in Toybox → Boombox → Lock Sound. (2) Your USB drive must be formatted FAT32 or exFAT and the file must be at Boombox/LockChime.wav exactly. Lock the car from the app to test.
What firmware do I need for a custom Tesla lock sound?
Custom lock sounds have been available since Tesla's 2023 Holiday Update (software 2023.44) — virtually every Tesla on current software supports them. Model 3 (built Sept 2019+), Model Y (all years), Model S / X (2021 refresh+), and Cybertruck (all) are supported. If you don't see the Lock Sound option, update from Controls → Software.
What file format does LockChime.wav need to be?
Tesla requires a WAV file named exactly LockChime.wav. The 44.1kHz, 16-bit PCM spec and 1–5 second duration are recommended for clean playback — not an official Tesla requirement. Every download on TeslaLockSound already meets these specs.
Does changing the lock sound affect Tesla's horn?
No. The Boombox lock-sound chime is completely separate from the horn. Horn sounds are in a different Boombox menu. Your LockChime.wav only affects the lock chirp.
Is it free to download Tesla lock sounds from TeslaLockSound?
Yes. Every sound on TeslaLockSound is free — no account, no email gate, no paywall. Click any card to preview, then download as a Tesla-ready LockChime.wav.
